Abstract (en)

[origin: EP2618119A2] The method involves determining the color difference (delta R) between the two color vectors (E1,E2). A basic color vector is determined by one of the two color vectors or by combining the two color vectors in color space (R). A multiplier (delta E) is determined by selecting from multiple multipliers based on the basic color vector. The perceptible color difference or the color fidelity is determined as a color difference product and the multiplier product. An independent claim is included for a device for determining the color fidelity and for determining the human perceptible color difference between two colors provided by color vectors.
